   Which characteristic distinguishes TCP from UDP?

   • ATCP is used for streaming video, while UDP is used for web browsing.
   • BTCP is faster than UDP because it uses smaller headers.
   • CTCP uses broadcast addressing, while UDP uses multicast addressing.
   • DTCP is connection-oriented and provides reliable delivery; UDP is connectionless and does not guarantee delivery.

   An engineer is designing a communication link between a remote RTU and a central historian. The RTU sends small, periodic status updates every 5 seconds. The engineer must choose a transport protocol. Which protocol should be used and why?

   • ATCP, because it provides flow control to prevent the historian from being overwhelmed.
   • BTCP, because it guarantees delivery and ordering of the status updates.
   • CUDP, because it guarantees that updates arrive in the correct order.
   • DUDP, because it has lower overhead and the loss of an occasional status update is acceptable.
